>Description:
This computer is configured as a NFS server and it also has IPSEC enabled.  When a NFS client accesses this server, the server imediately panics with the following error "panic: nfssvc_nfsd(): debug.mpsafenet=1 && Giant" and reboots hanging the client.  On a release 6.0 machine, debug.mpsafe is forced to 0 because IPSEC requires Giant.
>How-To-Repeat:
On a 6.1 system, enable IPSEC and NFS then try to access the server remotely.
>Fix:
Can't.  The OID for debug.mpsafenet is readonly.
